IMPROVEMENT IN CARRIAGE-SPRING.

TO ALL WHOM IT MAY CONGERNz Be it known that I, JOSIAH R. LOCKE, of thecity and-county of San Francisco, State of California, have invented anImproved Carriage-Spring; and I do hereby declare the followingdescription and accompanying drawings are suflicient to enable anyperson skilled in the art or'science to which it most nearly appertainsto make and use my said invention or improvementwithout furtherinvention or experiment.

My invention consists in providing a light, easy, and durable spring forcarriages or buggies. The spring is constructed partly of wood andpartly of metal, so arranged and applied as to impart to it the greatestelasticity without impairing fits usefulness. There are two springs ateach side of the wagon, attached to the bottom of the bolster at oneend, and the axle-bed at the other, around which they pass in a gracefulcurve to the side rail of the carriage, where they separate in oppositedirections by a goose-neck curve, in which position they are bolted tothe side rail. Back of each of these springs is placed a smalldouble-acting spring,'the upper portion being attached to the rail, andthe lower working in a slide.

To more fully explainmy invention, reference is had to the accompanyingdrawings, forming a part of this specification, which shows a side viewof the springs and their attachment to the frame on one side of the buggA A represent the front and back springs, extending from the lower endsof.the reach, passing around the bolster and axle-bed to the raii or bedB of the buggy, to which they are bolted, forminggoose-neck curves D D,in opposite directions. The outer portion of the spring is steel, a, andpasses around'the wood spring a, near the upper or thick end, 6, atwhich point the wood portion is gradually curved to a thin edge. Thegooseneck springs are also constructed ofsteel, and pass down aconsiderable distance below the top steel spring, so that the woodspring is held between the two steel springs t9 furnish strength at theneeded points. i

The wood in the curves or cs are shaved thin, so that in connection withthe steel plate around it, sufficient strength and elasticity are had.-

Near the thick part of the springs A are attached slides E E, in whichthe double-acting springs F F work, the lower endacting on the uppersteel face of the spring a, and entering the slide band. The oppositeend is curved, and extends down to near the face of the spring, belowthe slide, so that when the buggy is heavily loaded, these curved endswill gently strike upon thesprings beneath, and the springs, one actingagainst another, produce the'efl'ect of a coil-spring,-which will carrydouble the load of the common elliptic spring of the same weight, andnot affect the reaches of the wagon.

Figure 2 shows, in red, a device which'may be employed to prevent thewagon from spreading laterally.

By this combination and arrangement of springs, a wagon of great case isbad, and very simple in construction.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is 4 1. In combination with the wood and steelsprings A A, the goose-neck springs D D, constructed substan- I tiallyas described.

2. The double-acting springs F F and the slides Edit, in which the lowerends move, or equivalent device, the whole constructed to operatesubstantially as described.

In witness whereof, I have hereunto set my hand and seal.
